Email receiving problem

Our T1 line connection was unavailable for 24 hours due to office moving. Now got the connection back but we can't receive any emails. The email server works fine, we can email internally. I can send emails outside but can't receive. I tested the MX records and they look fine.

 Any help would be much appreciated.

Thanks!

Have you tested the MX records from the outside?

I can telnet to port 25 from inside the network but not from outside. I'm looking into the firewall and the port it's not blocked. Is it possible to be blocked by the ISP?

 Thanks!

Have you tested your Router/Firewall? It seems to be blocking/not forwarding your connections from outside the network.

I don't see any problems with the firewall. Everything looks normal. How should I test it to see if there is a problem with it.

Thank you very much for your help!
